Data Sheets

N5191A1 UXG X-Series Agile Signal Generator, Modified Version

10 MHz to 20 or 40 GHz

Definitions and Conditions Specification (spec): represents warranted performance of a calibrated instrument that has been stored for a minimum of 2 hours within the operating temperature range of 0 to 55 °C, unless otherwise stated, and after a 1 hour warm-up period. The specifications include measurement uncertainty. Data represented in this document are specifications unless otherwise noted.

Typical (typ): describes additional product performance information. It is performance beyond specifications that 80% of the units exhibit with a 95% confidence level at room temperature (approximately 25 °C). Typical performance does not include measurement uncertainty.

Nominal (nom): describes the expected mean or average performance, or an attribute whose performance is by design, such as the 50 Ω connector. This data is not warranted and is measured at room temperature (approximately 25 °C).

Measured (meas): describes an attribute measured during the design phase for purposes of communicating expected performance, such as amplitude drift vs. time. This data is not warranted and is measured at room temperature (approximately 25 °C). All of the above apply when using the instrument in its default settings unless otherwise stated.

This data sheet provides a summary of the key performance parameters for N5191A modified UXG signal generators. All options referenced in this data sheet are described in the N5191A modified UXG configuration guide (5992-1116EN).

Unless otherwise noted, this data sheet applies to units with serial numbers ending in 5646XXXX or greater and firmware Revision A.01.86.

Normal mode

Normal mode is optimized for maximum update rate (throughput). If the fast control port (FCP) Option CC1, CC3, or CC4 is installed, it provides the capability to use pulse descriptor words (PDWs) to control frequency, amplitude, phase, pulse (include chirp or phase coding), and FM or ϕM. With CC1, the PDW is streamed into the rear-panel FCP 100-pin connector using 46-bit wide control words. The control word information is executed synchronously upon receipt of a trigger.

Fast CW mode

Fast CW mode is optimized for minimum latency. The FCP control over signal attributes is limited to CW frequency switching and the addition of FM/ϕM provided this option was purchased. It is typically used with the FCP Option CC2 for compatibility with instruments used in legacy test systems. When using the CC1 Interface Card, Option FR1 is required.

PDW streaming mode

Streaming provides agile control of most of the instrument settings via a continuous stream of PDWs transferred from the internal SSD or an external source, such as a LAN or the Fast Control Port (with Option CC3 or CC4). The set of parameters controlled by Streaming include frequency, frequency band map, band adjust, relative power, phase, phase mode, pulse, pulse start time, FM (chirp) and PM (phase coding). Each PDW consists of seven 32-bit words. The streaming PDW parameters are executed asynchronously, based on the time stamp information contained within the PDW. Option PM2 is required to stream.

List mode

List mode lets you play out a list of PDW’s located in and read from the instrument’s FPGA memory. The memory contains a series of list points where each list point contains multiple signal attributes. This mode supports dynamic sequencing using the external trigger ports.

Phase noise

Phase noise is measured using a CW signal at +10 dBm or maximum specified power, whichever is less, with spur optimizations off. Phase noise specifications exclude external mechanical vibration

Pulse modulation (Option PM2)

For frequencies from 400 MHz to 1.43 GHz, pulse modulation specifications apply in Mode B only. For frequencies below 400 MHz, pulse modulation is not specified.
